This episode was good in itself, even if the overall plot didn't advance at all. It was half about Jessica's new client, and half about finding witnesses and the cop trying to reconcile himself. The only problem was that the latter didn't seem particularly necessary and didn't accomplish much, although there were some great scenes between the cop and Trish that made up for that. The other half of the episode, revolving around Jessica's new client, was where this episode really shined. There was a continual sense of mystery around what was really going on with this client, and for once in this show it was hard to figure out what was going to happen next. The conclusion to this storyline, which was very self-contained, was a high for this series and also can now be seen as a close link to Captain America: Civil War (Jessica even backed this up by mentioning the Avengers).
Overall a good episode (that unfortunately was nothing more than filler), even if it was a shame that we didn't get another look at Kilgrave; and the reveal at the end was certainly unexpected.
